Engraving is the process that is used to create ÄRMs . It turns normal jewelry and objects into items with special abilities. Any ÄRM that posses magic power was created by the sorcerers of Caldia who downloaded that magic power into them. So any ÄRM that has magic stones put in it originated from Caldia. But normal Weapon ÄRMs that don't use any magic power can be created by an engraver.
